Cobalt-aluminum magnetic materials with high coercive force

ABSTRACT

Magnetic materials having large coercive force consist essentially of 66 to 95% by weight of Co, 5 to 25% by weight of Al, and a small but effective amount of at least one of Ti, Mo, Cr, V and W, the amount of the third metal being effective to increase the coercive force substantially above the coercive force of the same Co-Al alloy without that third metal.
